Tips

By default the column sizes in the rqt_topic view are automatically resized based on the width of the content. If you prefer to adjust the column widths manually you can right-click on the table header and select *Toggle Auto-Resize* to switch between automatic and manual mode.

Known issue

When monitoring topics that carry large amount of data (e.g. sensor_msgs/Image), the whole rqt process or even the entire OS might get slow down.

For other issues, please check the existing/closed tickets on the issue tracker.
